CrFeO3 is synthesized without any precipitating agent and chosen as a model material to study the validity of humidity sensing properties. The surface morphology and structural analysis are provided using field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), X‐ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) analysis. Elemental analysis is provided with the help of X‐ray photoelectron spectroscopy (XPS). Obtained results demonstrate the tunable response of order 860 and stability in a large range of humidity. Also, by controlling the porosity and film uniformity, a fast response time of 1.6 s and a recovery time of 2.6 s are achieved with very low hysteresis. Also, cole–cole plot and Fourier transform infrared spectroscopy (FTIR) spectra in the presence and absence of humidity provide detailed analysis of surface interaction with H2O molecules. In addition to this, the developed sensor demonstrates excellent response and reproducibility toward real‐time human respiration monitoring along with non‐contact sensing. This work enables the study of developed sensors in real‐time humidity monitoring for practical applications.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"73 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141786234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The air–vapor flow is modeled as a mixture by the Reynolds‐averaged Navier‐Stokes equations with the mixture species transport and the Eulerian wall film model using FLUENT. Particle flow is modeled by the Lagrangian particle tracking method and the condensational growth of particle droplets is modeled via a user‐defined function. The model is validated by reaching good agreement with experimental results. Flow field analysis shows that the added vapor does not change the major vortex characteristics in the cyclone, but the vapor distribution is not uniform. The vapor concentration is much higher in the upper part than in the lower part of the cyclone, leading to insufficient condensational growth in the lower part. A secondary vapor injection is proposed to improve the vapor concentration in the lower part, which is shown to be effective in improving the collection efficiency. The model and the results are helpful to the understanding and optimization of the CAP cyclone technology, and also the vapor and particle droplet flow in turbulent flows.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"32 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141784227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, use of therapeutic secondary metabolites (SMs) from Actinobacteria as new drugs presents a promising avenue.

Even though nanosuspension technology has been effectively used to address these challenges, use of this technology for nanox02010;listed priority pathogens has made development of new antibacterial agents a critical priority. In thitransformation of crude metabolites from Actinobacteria is still an unattempted area. Herein, for the first time, development of water‐soluble nanosuspension of water‐insoluble therapeutic metabolites produced by Streptomyces californicus strain ADR1 to develop a biocompatible material to be used as potential nanomedicine is reported. The nanosuspension (N‐SM) is characterized by UV‐vis spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and dynamic light scattering (DLS). The nanosuspension reduces the MIC values by 50% against Gram‐positive priority pathogens and eradicates established biofilms with fivefold efficiency incomparison to SMs. The nanosuspension also displays antioxidant activity. The findings open up future possibilities of using this novel nanosuspension as an effective antibacterial agent in various therapeutic and biomedical applications like wound dressings, coatings on medical equipment, and surgical implants.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"24 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141575381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, cuprous oxide shell growth on nanosized prism‐shaped gold nanoparticles is investigated, where the core‐particle morphology does not match the prototypical cubic or octahedral symmetry of the embedding cuprous oxide particle. It is shown that different shell morphology is obtained depending on the reducing agent used for the shell deposition. Strong reducing agent (hydrazine) leads to a multi‐slab‐like coating with smooth facets, while under milder conditions (hydroxylamine) a multi‐grain coating is obtained. Successful realization of time‐dependent spectroscopic and structural investigations indicate that in this latter case cuprous oxide shell growth is initiated site‐selectively, namely in the highly curved regions of the particle, with a higher growth rate around the tips of the nanoprisms. This is supported by correlative single‐nanoparticle spectroscopy/scanning electron microscopy measurements, that allow to establish the connection between the optical properties and the structure of these plasmonic/semiconductor core/shell nanoparticles.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"16 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141549439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A promising approach is the storage of CO2 in minerals, of which Olivine is a promising candidate due to its Earth abundance and high CO2 absorption capacity, which is of the order of 50 wt.%. A bottleneck for Olivine carbonation is the slow reaction rate at ambient conditions, which previously resulted in supplying CO2 at extreme pressures and temperatures to force carbonation. In this study, nanoscale Olivine particles are fabricated, which due to their high surface‐to‐volume ratio, reach a very high carbonation conversion at a time scale of minutes at ambient conditions. The carbonation is measured by X‐ray photoelectron spectroscopy (XPS), which yielded both the presence of carbonates as well as information on the Olivine oxidation state, in agreement with electron diffraction analysis. This work forms the basis for employing Olivine nanoparticles, as fabricated by the relatively simple method of magnetron sputtering, to capture CO2 from the atmosphere at economic conditions.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"4 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141549438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current chemotherapy is often hampered by side effects, tissue damage, and drug resistance. To overcome these limitations, research is exploring new approaches to improve chemotherapy efficacy and reduce its side effects. A promising strategy involves combining chemotherapeutic drugs with phytochemicals, which are active compounds derived from plants. Nanotechnology plays a crucial role in delivering these often‐hydrophobic drugs, enhancing their bioavailability and solubility. This research area represents a significant convergence of nanotechnology with both conventional pharmaceuticals and botanical compounds. Global studies are increasingly demonstrating the potential of these combination therapies to inhibit cancer cell growth in laboratory and preclinical models. These studies suggest synergistic or additive effects that lead to improved treatment outcomes. This article focuses on recent advancements in nano‐drug delivery systems, specifically those designed for the simultaneous delivery of chemotherapeutic drugs and phytochemicals. It explores the selection of phytochemicals based on their anticancer properties, outlines the design considerations for nanocarriers, and discusses how physicochemical characteristics influence drug release kinetics.

After that, the ability of ZnO‐QDs as an antibacterial and antibiofilm agent against methicillin‐resistant Staphylococcus aureus (MRSA) is examined. The 100 samples are collected from patients with hospital‐acquired infections between December 2020 and October 2021 from Imamen Kadhmiyan Teaching Hospital in Baghdad (Iraq). Out of these 100 samples, 63 are S. aureus and 20 out of 63 are MRSA. The minimum inhibitory concentration assay demonstrates the antibacterial activity of ZnO‐QDs on MRSA strains. Also, results show that 80, 5, and 15% of isolated MRSA strains produce strong, moderate, and weak or very weak biofilm, respectively. The effect of ZnO‐QDs on strong and moderate biofilms reveal that QDs could also inhibit and destroy biofilm produced by MRSA. In addition, the antibiofilm effect of ZnO‐QDs is greater than their antibacterial effect. Generally, this work offers new insights into the development of antibacterial and antibiofilm nanomaterials.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"201 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, identifying these biomarkers remains difficult and expensive. Advancements in extracellular vesicle techniques, including single extracellular vesicle characterization, hold promise for disease diagnosis and personalized medicine. Notably, the biomechanical properties of extracellular vesicles have emerged as a potential diagnosis tool. However, biomechanical characterization has rarely been investigated for disease diagnosis due to limited understanding and a lack of standardized protocols.

Temperature measurements using a thermocouple and by optical emission spectroscopy showed that, while the overall temperature of the wire is very high, it is not in the range of the melting temperature of tungsten; however, it can reach values needed for sublimation. Additionally, the wire is heated selectively while the temperature of the jet components reaches only a few hundred degrees Celsius.
